Specification of Letters Patent.

Patented Aug. 21, 191?.

Application filed June 9, 1916. Serial No. 102,686.

To all whom it may concern:

Be it known that we, VERN SLATER and LEONIDAS D. Wnsr, citizens of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Fume-Disseminators;and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention which relates to improvements in devices for disseminating fumes from liquids such as deodorizers, disinfectors, medicines and the like, has for its princiaal object to provide a simple yet highly e cient absorbent member adapted to be saturated with the liquid from which the fumes are to be taken, said member being adapted for disposition in a casing through which a current of air is directed, whereby the fumes of the liquid with which it is saturated will be delivered with said air.

With the foregoing general object in view, the invention resides in certain novel fea tures of construction and unique combinations of parts to be hereinafter fully described and claimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this ap plication and in which:

Figure 1 is a vertical section of the im proved device;

Fig. 2 is a horizontal section on the plane of the line 22 of Fig. 1; and

Fig. 3 is a perspective of the absorbent block to be saturated with the liquid to be disseminated? M Tn specifically describing the structure shown in the drawing above briefly described, similar characters will be employed to designate corresponding arts throughout the several views and re erence will be herein made to the numerous elements by their respective indices.- To this end, the numeral 1 designates a cylindrical casing which is shown rising from a base 2, the upper end of said casing being partially closed by a top 3, which top includes a sheet metal ring 1 fitting into said upper end of the easing 1 and having its upper edge bent downwardl and inwardly to provide a frustocone s aped flange 5 which is perforated as indicated at 6. A horizontally disposed disk 7 1s spaced above the ring 4 and its flange 5, said disk being perforated as indicated at 8 and being supported by legs 9 which depend therefrom and are secured to the ring.

An electric motor 10 is supported by the base 2 within the lower end of the casing 1, the upper end of said motor carrying a partition 11 which substantially fills the cross sectional area of said casing, suficient space being left, however, to permit air to pass downwardly around the edge of said partition to cool the motor 10. The vertical shaft 12 of motor 10 carries any desired type of fan 13 which is adapted to discharge air from the interior of the casing 1 through an outlet nipple 14 disposed between the ends thereof, and in thus discharging air other currents of air will necessarily flow intothe casing through the top 3 to occupy the partial vacuum caused therein. Thus, it will be observed that air. will be constantly drawn into and discharged from the casing 1, this air being directed to the eye of the fan 13 by means of an annular partition 15 directly above said fan, this partition being suitably constructed for performing its function.

A plurality of brackets or abutments 16 are secured to the inner side .of the casing 1 immediately above the partition 15 and serve to support an absorbent cylindrical block 17 which will be saturated with the liquid from which fumes are to be taken. It is of course obvious that although the abutments 16 are shown, one continuous abutment or ledge might'well be employed for supporting block 17. In either case, the latter will substantially fil 1 the casing 1 between the top 3 and partltion 15 and will be formed with a plurality of vertical passages 18 through which the 'air must be drawn before being discharged through the nipple 14, whereupon this air will become impregnated with the fumes from the liquid used.

The block 17 is preferably constructed of a porous mineral known as tripoli since this has been found by actual experience to produce better results than other porous members, but in some forms of the invention this material may be obviously varied. The mineral fromwhich block 17 is constructed is extremely fra 'le and in order to shield the same' against reakage, an openwork hous;

ing 19 is provided therefor, said housing comprising a band 20 ofsuitable mesh woven wire which circumscribes said block, a top 21 and bottom 22 of the same material, and angle metal rings 23 whose horizontal and vertical flanges receive therein the meeting portions of the band 20 and the top and bottom 21 and 22, the wire members being' soldered or otherwise secured to said flanges. By constructin this manner, the block 1 will be efiectively guarded against breakage and it cannot be mutilated by contact with the abutments 16 since the lowermost ring 23 rests on said abutments. In order to remove the block 17, a suitable handle 24 is preferably connected with the center of the housing top 21.

The block 17 may be saturated by removing the same from the casing 1 and immersing it in the liquid to be used. This liquid may be poured upon the block, or a constant supply device may be provided for dripping the liquid upon the block when the latter is in use. Such'a device is indicated in Fig. 1 in the form of a valved passage member 25 which depends from any suitable type of reservoir 26, the lower end of said passage member being threaded through a central opening in the disk 7. The supply of this liquid may be controlled by the valve 27 as will be readily understood'and may if desired be cut olf entirely.

The improved device constructed substantially as shown and described will be well adapted for a number of uses and is particularly applicable for the purposev of avoiding close andoppressive odors in rooms wherein a number of persons assemble. In such places, although not so perceptible to the occupant, the air is quite unpleasant to a new arrival from the fresh air, butthis difiiculty may obviously be overcome to great advantage by employing a suitable deodorizer or perfume in the block 17. The apparatus is equally well adapted for disinfecting sick rooms,and others and may well be used in such places for supplying a quantity of medicated air. The foregoing are merely an illustration ofthe many uses and it will be-obvious that regardless of the manner in which the device is employed, it will be highly eflicient and will fulfil long felt needs.

In conclusion, we will state that although we have shown and described a number of specific details of construction for the attainment of probably the best results, numerous changes may be made within the scope of the invention as claimed without sacrificing the main advantages thereof.

We claim: 1. A vertical continuous casing, closed at its bottom and providing for a top chamher, a bottom chamber and an intennediate.

suction chamber, with an air inlet for said the housing 19 in 1,2ss,oes

top chamber and an exhaust for said suction chamber, in combination with a mass of porous material, freely absorptive as to an impregnating agent, said mass being suitably contained within and substantially filling said top chamber, between said air inlet and suction chamber, air passages being'provided for the flow of impregnated air into said suction chamber; a rotary fan blower horizontally disposed in said suction chamber, with its vanes-operating in horizontal alinement with said exhaust and its eye directly beneath and facing said absorptive mass; and a niotor in said bottom chamber operatively connected to said blower, the elements being arranged, combined and functioning, substantially as set forth.

2. The combination of a vertical continuous casing having a closed bottom and an air inlet at the top; a motor in the bottom of said casing; a partition above said mo-' tor; an exhaust outlet for said casing immediately above said partition; a horizontally disposed rotary fan blower, connected tosaid motor, located above said partition with its vanes operating in horizontal alinement with said exhaust outlet and its eye facing upwardly; a second partition element immediately'above said exhaust and said fan blower and apertured to provide a discharge opening. directed to the eye of said fan blower, said partitions providing a restricted suction chamber, incasing said fan blower, intermediate of the ends of the casing; and a mass of porous material, freely absorptive as to an impregnating agent, said mass being suitably contained within and substantially filling said casing, between said air inlet and suction chamber, air passages being provided for the flow of incoming air through and around said mass and into said suction chamber. through the opening in said upper partition, the several elements being alined, combined and functioning, substantially as set forth.

3. A fume disseminator comprising an upright cylindrical casing having in its upper end one or more air inlets and having near its lower end an air outlet, a fan in the lower end of said casing for drawing air into the same and discharging it through said outlet, and a plurality of abutments secured to the wall of the casing and projecting inwardly therefrom in a vertical plane spaced above the fan; in combination with a cylindrical block of absorbent frangible material disposed in said casing and spaced a slight distance from the wall thereof, said block having formed vertically therethrough a plurality of air passages, a
